| Abstract: | Josephsen junction mixer has much excellence, including its high sensitivity and harmonic, low local oscillator frequency and microwave power, low noise and wide frequency band. The cryocooler can be used as a cooler of the high temperature superconductor mixing measurement system. We have designed and made a new HTS mixing systern mounted on the cryocooler. Some measures have been taken to decrease the system noise. With HTS Josephsen junction as the mixing element, 50th harmonic frequency mixing at 3mm wave band is obtained on the system. |
